microbiota metabolites, urolithin A (Uro-A) and urolithin B (Uro-B). These compounds exert
anti-inflammatory effects in vitro and in vivo. The aim of this study was to investigate the
effects of Uro-A, Uro-B, and EA on colon fibroblasts, cells that play a key role in intestinal
inflammation. CCD18-Co colon fibroblasts were exposed to a mixture of Uro-A, Uro-B, and
EA, at concentrations comparable to those found in the colon (40 μM Uro-A, 5 μM Uro-B, 1 …
